Check Digit Verification of cas no
The CAS Registry Mumber 721388-02-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,2,1,3,8 and 8 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 721388-02:
(8*7)+(7*2)+(6*1)+(5*3)+(4*8)+(3*8)+(2*0)+(1*2)=149
149 % 10 = 9
So 721388-02-9 is a valid CAS Registry Number.

RADICAL STABILISATION: SYNTHESIS AND DECOMPOSITION OF A β-KETODIAZENE
Zavalsky, Robert C.,Lisiak, Michael,Kovacic, Peter,Luedtke, Al,Timberlake, Jack W.
, p. 425 - 428 (1980)
The synthesis and decomposition of bis(1,1-dimethyl-2-oxo-2-phenylethyl)diazene (7e) is described.The presence of a carbonyl group adjacent to a radical center greatly enhances the radical stability.
